## **About Grid**
We founded Grid to design future-proof solutions for financial firms and startups struggling to keep pace with the breakneck advance of fraud tactics. A new player in the fraud prevention space with deep roots in financial business management, we came by our mission the hard way.
After our consumer business fell victim to one of the infinite variations of fraud, our co-founders set out to create a platform that’s more of a fortress than a tool — saving our clients millions in annual revenue and a ton of restless nights. The result? A fraud prevention platform that integrates multiple data providers into a single, powerful solution designed for rapid deployment and ease of use.
## **About the Role**
- Build robust, fault-tolerant integrations with 3rd party APIs that have little to no or poor documentation.
- Create sophisticated background processing pipelines that are also fault-tolerant.
- Develop mature APIs and microservices that adhere to RESTful principles that are used by paying clients in production.
- Write strong unit and integration tests that ensure the code quality of your work.
- Investigate client issues and service disruptions that require a deep dive.
- Translate high-level requirements into a system design update and new data model while collaborating with clients and team members through requirements gathering and discovery.
- Evaluate the pros and cons of high level architectural choices as well as lower level design decisions required within an existing application.
- Work autonomously and make system design decisions that are resistant to change leveraging your experience.
- Deeply invested in your work and client happiness.
- Mentor junior to mid level engineers while also holding them accountable.
